Fig. 1

Spectra of a selected sample of stars with near-solar metallicity displayed in decreasing temperature sequence from top to bottom. The spectra of a few metal-poor stars are superposed on solar-metallicity stars of similar temperatures. The atmospheric parameters Teff, log g, and [Fe/H] for each star are given in parenthesis.
